Python - isort + autoflake

# 安装
pip install isort autoflake
# 清理单个文件
autoflake --in-place --remove-all-unused-imports file.py
isort file.py
# 批量清理所有Python文件
find . -name "*.py" -exec autoflake --in-place --remove-all-unused-imports {} \;
find . -name "*.py" -exec isort {} \;

JavaScript/TypeScript - ESLint

# 安装
npm install -g eslint eslint-plugin-unused-imports
# ESLint配置
// .eslintrc.json
{
  "plugins": ["unused-imports"],
  "rules": {
    "no-unused-vars": "off",
    "unused-imports/no-unused-imports": "error"
  }
}
# 批量修复
eslint --fix "src/**/*.{js,jsx,ts,tsx}"

Java - IntelliJ IDEA 插件

# 使用IntelliJ IDEA的"Optimize Imports"功能
# 快捷键: Ctrl+Alt+O (Windows) / Cmd+Option+O (Mac)
# 或使用Maven插件
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <configuration>
        <includes>**/*.java</includes>
    </configuration>
</plugin>

Go - gofmt + staticcheck

# 安装
go install honnef.co/go/tools/cmd/staticcheck@latest
# 清理未使用导入
go fix ./...
go fmt ./...
staticcheck -checks="U1000" ./...

通用方法 - 使用脚本批量处理

# batch_clean_imports.py
import os
import subprocess
def clean_python_imports(root_dir):
    """清理Python项目中的冗余导入"""
    for dirpath, dirnames, filenames in os.walk(root_dir):
        for filename in filenames:
            if filename.endswith('.py'):
                filepath = os.path.join(dirpath, filename)
                # 使用autoflake清理
                subprocess.run([
                    'autoflake', 
                    '--in-place', 
                    '--remove-all-unused-imports',
                    filepath
                ])
                # 排序导入
                subprocess.run(['isort', filepath])
def clean_js_imports(root_dir):
    """清理JavaScript/TypeScript项目中的冗余导入"""
    for dirpath, dirnames, filenames in os.walk(root_dir):
        for filename in filenames:
            if filename.endswith(('.js', '.jsx', '.ts', '.tsx')):
                filepath = os.path.join(dirpath, filename)
                subprocess.run([
                    'npx', 'eslint', '--fix',
                    filepath
                ])
if __name__ == "__main__":
    project_root = "./src"
    clean_python_imports(project_root)

IDE内置功能

Git Hooks 自动清理

# .git/hooks/pre-commit
#!/bin/bash
echo "Running import cleanup..."
# Python
find . -name "*.py" -exec autoflake --in-place --remove-all-unused-imports {} \;
find . -name "*.py" -exec isort {} \;
# JavaScript/TypeScript
npx eslint --fix "src/**/*.{js,jsx,ts,tsx}"
git add -u

CI/CD集成

# .github/workflows/clean-imports.yml
name: Clean Unused Imports
on: [push, pull_request]
jobs:
  cleanup:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Clean Python imports
        run: |
          pip install autoflake isort
          find . -name "*.py" -exec autoflake --in-place --remove-all-unused-imports {} \;
          find . -name "*.py" -exec isort {} \;
      - name: Clean JS imports
        run: |
          npm install -g eslint eslint-plugin-unused-imports
          npx eslint --fix "src/**/*.{js,jsx,ts,tsx}"
      - name: Commit changes
        uses: stefanzweifel/git-auto-commit-action@v4

推荐工作流

1. 配置自动化工具：在项目中配置所需的工具
2. 添加到package.json：

   {
     "scripts": {
       "clean-imports": "autoflake --in-place --remove-all-unused-imports src/**/*.py && isort src/**/*.py",
       "precommit": "npm run clean-imports"
     }
   }

3. 定期执行：在开发流程中定期运行清理命令

选择合适的工具取决于你的技术栈,建议在项目初始化时就配置好这些自动化工具，避免冗余导入积累。
